3M 4664-6201 Rectangular Connector Plug - Equivalent & Substitute Parts

Part Overview

The 3M 4664-6201 is a 64-position rectangular plug connector with IDC (Insulation Displacement Contact) termination, designed for discrete or ribbon cable applications. This connector features gold-plated contacts rated for 26-28 AWG wire gauges and is configured as a free-hanging, in-line component with latch lock/eject hook fastening. The part maintains Active product status and is RoHS3 compliant, making it suitable for current industrial and commercial applications where reliable rectangular connector solutions are required.

Substitute parts are identified when inventory constraints, lead time considerations, or application-specific requirements necessitate alternative sourcing options that maintain equivalent electrical and mechanical performance.

Substitute Part Grouping Explanation

Substitution eligibility for the 3M 4664-6201 is determined by strict equivalence across the following critical parameters:

• Connector Configuration: 64-position plug with male pin contacts
• Contact Pitch and Row Spacing: 0.100" (2.54mm) in both dimensions
• Termination Method: IDC technology for discrete or ribbon cable
• Wire Gauge Compatibility: 26-28 AWG, supporting both stranded and solid conductors
• Contact Material and Finish: Gold plating at 30.0µin (0.76µm) thickness
• Mounting and Fastening: Free-hanging, in-line configuration
• Compliance Standards: RoHS3 compliance and MSL 1 rating

The identified substitute part maintains all critical electrical and mechanical parameters, ensuring direct functional equivalence without design modification or performance degradation.
